// module.02 · capabilities

Systems design as a
first-class discipline.

Six capability nodes. Each backed by a stack we've run in production, methodologies we've written down, and measurable outcomes we've delivered.

node.SYS.01● active

Integrated Systems Design

Bind legacy monoliths to modern platforms with zero-downtime migration paths and reconciliation harnesses.
